为什么web service 调用远程数据的时候就提示remoting已关闭？

[lanxe]

如果是调用web service 上不是从SQL读取的数据就可以，
一碰到SQL读取的就提示以下信息：
the underlying connection was closed: unable to connect to the remote server.


同时在别的机的时候，直接用http访问也是提示：
The test form is only available for requests from the local machine.

我自己在本机浏览asmx页面的时候，也是只能浏览到函数，一执行invoke 就提示System.IO.FileNotFoundException: File or assembly name ysuolcf6.dll, or one of its dependencies, was not found.
File name: "ysuolcf6.dll"（这个dll文件不停变）


请问这是什么原因造成的？

如果这个问题解决再送100分回报！

谢谢

it just try to read data from SQL only, it does not write any data. why it need ASPNET or Network Service permission?

what classes are you using to access teh database? the reason %windir%/TEMP is needed, because the system needs to do some i/o internally
